COAL-TIPPLE.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed January 18,1907. Serial No. 852,915.

To all whom it may concern:

Be it known that I, JAMns S. Paras, a resident of Monongahela, in thecounty of Washington and State of Pennsylvania, have invented certainnew and useful Improvements in Coal-Tipples, of which the following is aspecification.

Coal tipples now in general use are provided each with a holding barwhich is pivoted to and depends from the rear end of the tiltingplatform and cooperates with a holding device on the tipple structurefor controlling the upward movement of the platform, being operatedeither as a brake for causing the platform to move slowly, or forarresting its movement altogether. When the platform is tilted this baris elevated through the car approach, and it is not infrequent for carsto move toward the platform when the latter is raised, bumping into andbreaking the bar, as heretofore no means have been provided forprotecting the bar from such a blow. In fact the danger of breaking barsis so great that it is a common practice to have a supply of bars inreserve for each tipple, in readiness to replace those which are broken.

One object of the present invention is to. provide for a cushionedmovement or play of the bar in the direction of movement of anapproaching car, so that it may not only withstand the blow of a car,but also stop its forward movement.

A further object of the invention is to provide for cushioning the shockincident to the sudden stopping of the car when it reaches its positionon the tilting platform. Injury to the tipple, and particularly theoperating portion of the mechanism, is thereby avoided. This feature ofthe invention is preferably embodied in cushioned or yielding bearingsin which the tilting platform oscillates, thus cushioning the tiltingmechanism in its entirety, This cushioning of the platform alsocooperates in a measure with the bar-cushioning mechanism for yieldinglyresisting the blow upon the latter of an approaching car.

Still a further object of the invention is to provide improved mechanismfor operating the car-holding stops or horns.

In the accompanying drawings, Figure 1 is a side elevation, partiallybroken away, of a tipple constructed in accordance with the invention.Fig. 2 is a crosssectional view on line 2-2 of Fig. Fig. 3 is a view ona larger scale of the bar holding and cushioning mechanism, and Figs. 4and 5 are detail views of portions of the latter. Fig. 6 is a detailview of one of the platform bearings. Fig. 7 is a top plan view of thetilting platform, and Fig. 8 is an inverted plan view of the same.

Referring to the drawings, 2 designates the outside longitudinal timbersof the tipple structure, upon which are mounted the bearing slideways 3in which are slidable bearings 4 for trunnions 5 of the tilting platform6. The bearings are held normally in the rear ends of the slideways bysprings 7, the latter being confined each by a bolt 8 secured to thebearing and extending through one end of slideways 3 where it isprovided with nut 8. By this means the tension of the springs may, ifdesired, be regulated. Connected to platform 6 are the usual cross-overrails 9.

A tongue 10 extends rearward from the center of the platform, andoverhangs the tipple approach. Pivoted at 10 to this tongue is thedepending curved bar or sword 11, formed on its opposite edges with thealternately arranged stops or holding points 12 which cooperate with amovable holding device. This portion of the apparatus, as here embodied,is in accordance with reissue Letters Patent No. 12,553, granted to meNovember 6th, 1906.

Bar 11 operates through a casing 14, here shown secured to intermediatetimber 2 of the tipple frame. This casing is constructed with twohorizontal passages or slideways-one above the other. A slide 15 ismovable in the upper guideway, being formed with a passage 15 for bar11. This slide is reciprocated against the pull of spring 16 forengaging it with first one and then another of bar stops 12 forintermittently and suddenly stopping the ascent of the bar, and thusjolting the tilting platform for the purpose of shaking the coal fromthe car, all as described in my Letters Patent above referred to. Slide15 may be conveniently operated by link 17 connecting it to an arm 17 ofrock shaft 18, the latter carrying the upright operating lever 18.

In the lowermost slideway of casing 14 is guide 19 having a verticalpassage which in shape corresponds to the cross-section of bar 11, andas I prefer to form the bar with side ribs 11, the passage in the guidehas corresponding offsets 19. One end of the guide is provided with adepending lug 20, and a heavy spring 21 is confined on tensionregulating bolt 21 between this lug and the outer face of casing 14,thus holding the guide normally fixed, but permitting it and the bar tomove forward when the latter is bumped by an approaching car. The shockis thus arrested and the bar afforded such a compensating movement as tosave it from injury in many cases where otherwise it would be broken.This movement of the guide does not interfere in any way with theoperation ,of the bar-holding mechanism.

It is characteristic of the horn-operating mechanism of the presentinvention that it is all mounted on and movable with the tiltingplatform. I am aware that this is not broadly new, and claim noveltyonly for the improved arrangement of operating parts. The horns or carstops 22 each consists of a horizontal body portion having at one endthe raised Wheel-engaging pertion 23. The stop is mounted between itsends on a vertical pivot 24, with the end opposite the car-holding endconnected by link 25 with the inner end of bar 26, the latter beingmovable longitudinally of and secured to the under side of the platform(3. A spring 27 is connected to links 25 and normally holds the horns incar stopping position, with a stop 28 limiting the movement imparted bythe spring. The forward end of bar 26 is connected to the lower end ofvertical lever 29, the latter being fulcrumed between its ends to theextremity of tongue 10, and at its upper end carrying wheel 30. Thiswheel is adapted to be engaged by the under portion of a car approachingthe tilting platform and is rocked forward, thus operating the mechanismwhich connects with the pivoted horns in such a manner as to turn thelatter and release the previously emptied car and permit it to pass onto cross-over rails 9 as the next car passes onto the platform.

The platform with the emptied car may be lowered from tiltedposition bymeans of a power cylinder 31, having its piston connected by line 32with the platform.
